lMPROVEMENT IN MILLSTONE-BALANCES.

Specification forming part of Letters Patent No. 113$,d9fi, datedDecember 31, 1872.

To all whom it may concern:

Be it known that I, JOHN M. SCHRAM'M, of Pontoosuc, in the county ofHancock and State of Illinois, have invented a new and valuableImprovement in Devices for Balancing Millstones; and I do hereby declarethat the following is a full, clear, and exact description of theconstruction and operation of the same, reference being had to theannexed drawing making a part of this specification, and to the lettersand figures of reference marked thereon.

Figure l of the drawing is a representation of a front view of one of myhangers. Fig. 2 is a side view of the same. Fig. 3 is a front View ofthe opposite hanger. Fig. 4 is a side view of the same. Fig. 5 is a viewofa millstone with my devices attached.

This invention has relation to the means for balancing inillstones; andit consists in the construction and novel arrangement of adjustableweight-holding hangers, designed to be applied to the upper stone 'orrunner, substantially as and for the purpose hereinafter more fullydescribed.

Referring to the accompanying drawing, A A designate two hangers, eachprovided with an adjustable clamping-hook, B, having a lug, a,corresponding to and resting on a lug, a, at the top of the standard,and secured thereto by an adjusting-screw, b. The lower end of eachhanger is also constructed with a hook, b, similar to the clamp-hook.These hooks are used in securing the hangers to the upper and loweredges of the band encircling the run- The parts B are made adjustable,so that the standards may be applied to and rigidly secured to bands ofdifferent widths. The hanger A is provided with a plate, 1), heldoutward by means of arms D furnished with screw-holes or other means forthe attachment of pieces of lead used as a balancing material. The plateI) is located near the lower end of the hanger A. The hanger A isalsoprovided be first put in good train and drive, and the spindle tightenedto hold it steady. A stout rest is then fitted up above the back of therunner, from which to turn off the plaster back to make it true with theface. When the plaster is properly finished the runner is to be raisedabout one-half inch or an inch above the bed -stone, and started abovegrinding speed. A pencil is then held toward the outer edge of the stoneand against the rest until it touches the plaster back at the outer edgeof the stone. On the side where the pencil marks the greater proportionof weight will be found to be below the cock-eye. The hanger at thisside must, therefore, have its weight lessened by removing some of thelead. The stone is again rotated, and the pencil applied as be fore, andso on until the stone is put in true balance.

The plate E is designed to prevent the meal from filling up the spacebetween the curb and stone, and also to cool the meal and convey it tothe spout.

What I claim as new, and desire to secure by Letters Patent, is-- Thecombination of the hangers A A hav ing the adjustable clamps B, plates DD and hooks b, and applied to a mill runner-stone, substantially asspecified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
